Definitions

  • the present invention relates to a compacting station with at least one compacting device for compacting open sacks filled with bulk goods.
  • the invention is used in particular in connection with a device such as that described in US Pat WO 2016/046302 A1 have become known.
  • bags are filled, for example, with bulk materials such as cement, high-quality joint mortar or other building materials. Block-shaped bags with a high degree of compression are produced.
  • the filling weight of a filled open sack being between approximately 1 kg and 10 kg.
  • the bags can be produced directly in a device upstream of the device as part of the filling process. For this purpose, for example, a flat film is passed over a forming shoulder and the flat film is welded there to form a film tube.
  • the open bag to be filled is received in a receiving box and filled there.
  • the known device can Filling box-shaped open-top bags that are compacted during the process. At the end of the process, square open bags can be packed. The known device works satisfactorily.
  • the open sacks filled with bulk goods are picked up by many people or if the open sacks are pressed too hard (or fingered extensively with the hands), the sacks can soften and lose their exact cuboid shape.
  • a compression station comprises at least one compression device for the compression of open sacks filled with bulk goods.
  • the compression device comprises a container with a tubular inner wall and a receiving space for receiving a filled open bag.
  • a support unit is provided on a height-adjustable lifting device.
  • the support unit is adjustable in height relative to the container in particular by means of the height-adjustable lifting device. In a lowered position of the lifting device, the support unit is supported from below and, in a raised position, is suitable for taking over a filled open bag from an adjacent conveyor device.
  • a press ram that can be lowered from above is included, which in a lowered position acts on the bulk material from above and which, in a raised position, enables a filled open bag to be taken over from an adjacent conveyor device.
  • the compression station according to the invention has many advantages.
  • a considerable advantage of the compression station according to the invention is that a filled open bag is compressed within a container.
  • the shape of the container is impressed on the open bag. For example, square-shaped, filled open bags with a high degree of compression can be produced.
  • the support unit in a lowered position of the lifting device, is supported or set down on support hooks of the container and supported by them from below.
  • Other support from below is also possible.
  • the container can preferably be raised and lowered periodically by one container stroke via a compression gear.
  • a periodic raising and lowering of the container relative to the ram ensures a pounding or shaking compression of the bulk material filled into the open bag.
  • the container stroke is preferably less than a fifth and in particular less than a tenth of the length of the container.
  • the container stroke is less than 50 mm and in particular less than 20 mm and preferably less than 10 mm.
  • a stroke of 6 mm is used.
  • the stroke can be selected depending on the container size and in particular the container height and the desired degree of compression and the compressibility of the bulk material.
  • the ram is preferably driven by a pneumatic drive.
  • the pneumatic drive can comprise at least one pneumatic cylinder.
  • the compression gear is preferably driven by an electric motor.
  • the combination of a pneumatic drive and another, for example electric drive has the advantage that the Pneumatic drive can compensate for pressure surges, so that overloading is reliably prevented.
  • press ram is automatically adjusted with increasing compression (due to the pneumatics). Even with increasing compression, it is ensured that the acting force remains (practically) the same. Alternatively, it is also possible for the ram to stand still and the container to be raised and pneumatically adjusted.
  • a dedusting device is attached to the container. It is possible, for example, for the upper container opening to be at least partially surrounded by a dedusting opening.
  • dedusting gaps can be provided on one side of the container or on several sides of the container, which suction the upper area of the container and thus reliably remove a large part of any dust that may emerge.
  • an upper section of the container is conical or funnel-shaped or the like, so that it is easier to insert an open bag into the container.
  • the compression device is assigned a slide, swivel arm or the like, or the compression device has a slide with which the filled open bag can be pushed onto the support unit and / or back again laterally from, for example, the conveyor device.
  • an open bag to be compressed can be removed from the conveyor device and compressed in the compression station, while the conveyor device itself continues to run and, for example, transports a second filled open bag to a second compression device of the compression station.
  • the processing speed can be increased with a long dwell time in the compression station.
  • the slide includes suction cups in order to keep the upper bag wall open.
  • the slide preferably comprises suction cups at different heights in order to be able to keep the upper sack wall open in a targeted manner in each case of open sacks of different heights.
  • the support unit In all of the configurations it is possible for the support unit to be able to be raised using a short lifting device. This enables the support unit to be positioned slightly higher than the level of the conveyor when transferring a compressed open sack from the support unit to the conveyor, so that the already compressed open sack can be pushed off easily onto the conveyor. Conversely, the support unit can be placed slightly below the level of the conveyor device when an open bag to be compressed is transferred from the conveyor device to the support unit with the pusher.
  • the short stroke device can perform a stroke of 5 mm or 10 mm or 20 mm or an intermediate value.
  • the press ram is equipped with a suction device.
  • the compression station comprises at least 2 compression devices or 3 compression devices or more compression devices for compressing open sacks filled with bulk goods.
  • the compression devices are preferably arranged one behind the other and connected to one another via a conveyor device. This makes it possible to compress a filled open bag several times. In particular, however, it is also possible to compress a filled open bag at several compression devices at the same time, so that the processing speed increases accordingly.
  • the method according to the invention is used to compact bulk material in an open bag filled with bulk material.
  • a filled open bag is placed on a support unit.
  • the support unit with the filled open bag placed on it is lowered into a tubular receiving space of a container to such an extent that the product level is in the tubular receiving space of the container.
  • the support unit of the container then stands on support hooks or is supported from below.
  • a press ram dips into the open end of the open bag from above, at the same time or preferably beforehand, and acts on the bulk material from above, while the support unit (supported by the support hooks) presses against the bottom of the sack from below.
  • the lifting device moves in particular down and separates z. B. from the support unit when the support unit strikes the support hook.
  • the method according to the invention allows an advantageous compression of bulk goods in open sacks, whereby a parallelization to increase the performance of the overall system or a higher degree of compression of the overall system is made possible for a given overall output.
